In java please! as soon as pssble, should be simple code :) thank you!

Complete a generic class with the prototype below.

public class Choices{

// a class that represents either None or Some of a type. Add a private field as needed. (None indicates the absence of an item, some indicates the presence of a single item)

public Choices();

//construct a Choice which has a None of a type

public Choices (T item);

//construct a Choice which has Some which is the argument item

public boolean hasSome();

//returns true if the Choices has Some and false if it has None

public T getSome();

//if the Choices has Some, return the item it was constructed with. If the Choices has None, thrown a runtime exception with the message " Choices has None "

public String toString();

// if the Choices has Some, return a string formated "Some(XXX)" where XXX is repalced by the toString() of the item. If the Choices has None, return the string "None".

Explanation / Answer

I have written the Choices class.

I have considered type od some as String. If you want it in some different form you can have the same.

package com.example.Binsearch;

public class Choices {

private String some;

   public Choices() {
       super();
       // TODO Auto-generated constructor stub
   }

   public Choices(String choice){
       some=choice;
   }

   public boolean hasSome(){
       if(null==this.some||"".equals(this.some)){
           return false;
       }else{
           return true;
       }
   }

   public String getSome(){
       if(null==this.some||"".equals(this.some)){
           throw new RuntimeException("Choices has None");
       }else{
           return this.some;
       }
   }

   public String toString(){
       if(null==this.some||"".equals(this.some)){
           return "None";
       }else{
           return "Some("+this.some+")";
       }
   }

}
